THE MOUSE PAD OF MY TOSHIBA SATELLITE C855D-S5232 DID NOT MOVE (INTERMITENTLY) AND SO I INSTALLED A NEW WINDOWS 7 OS AND SINCE THEN I AM UNABLE TO DOWNLOAD VGA AND MOUSE DRIVERS IN ORDER TO BRING THE MACHINE TO ITS FORMAL STATE.

THE MOUSE SCROLLER IS NO MORE WORKING, THE GRAPHICS ARE NOT THE BEST - IN FACT WHEN I CONNECT TO A PROJECTOR, IT DOES NOT WORK.

The symptoms you describe after a clean Windows 7 install — touchpad scrolling intermittent and external projector not working — point to missing model-specific drivers and the laptop utility packages that restore special functions. Building on 's Device Manager idea and 's reinstall note, start by identifying exact devices in Device Manager (right‑click the device → Properties → Details → Hardware Ids). That tells you whether the touchpad is Synaptics/ELAN or just a generic PS/2 device and which graphics adapter is present. Use those hardware IDs when searching for drivers rather than guessing by model name alone.

Install drivers in this order: chipset first, then graphics (GPU), then touchpad, then the vendor hotkey/value‑added utilities. Chipset drivers ensure Windows recognizes buses and controllers; missing chipset support can break HID and video behavior. If the touchpad shows as “PS/2 Compatible Mouse,” install the OEM Synaptics/Elan driver for full scrolling and gestures. For the projector issue, a proper display adapter driver plus the Toshiba hotkey/utility package (enables Fn+display toggles) typically fixes external display switching — also use Windows+P to test once the driver/utility is installed.

Troubleshooting tips: uninstall any unknown HID/PS/2 entries and reboot to let Windows redetect, check BIOS/UEFI for an internal pointing-device enable/disable option, make sure you matched 32 vs 64‑bit drivers to your install, and avoid random third‑party sites — prefer the laptop maker or the component vendor (Synaptics/ELAN/AMD/Intel). If Windows Update doesn’t find the right driver, use hardware IDs with the Microsoft Update Catalog or the vendor download pages. If these steps still fail, collect the Hardware Id strings and vendor names and use them when seeking model‑specific driver packages or contacting Toshiba/Dynabook support.

i think your laptop can support win 7 and you should download latest drivers by downloading or by updating them through device manager . if you don't get laptop working get some friend help.as your laptop drivers problem can be sometime complex. Did you VISTA then drives of vista will probably work on windows7 (with some complexities sometimes)

Hi try re-installing Windows and make sure you remove the mouse when installing windows.
